Swiss watchmaker Oris is going for simplicity with the latest variation of its Big Crown ProPilot Worldtimer that hides its dual time zone function behind a buttonless design. A 20th anniversary update of the company’s 1997 Worldtimer, its bezel-operated complication allows the mechanical wristwatch to adjust the local time backwards and forwards in hour increments without the need to stop the mechanism or independently adjust the minutes or date.
